Subject: * ext/socket/socket.c (bsock_do_not_rev_lookup_set): should not be  
 allowed when $SAFE > 3.

* eval.c (rb_thread_ready): THREAD_TO_KILL threads should not turn
  into THREAD_RUNNABLE on wakeup.

* eval.c (rb_thread_list): THREAD_TO_KILL threads should be in the
  list.

* eval.c (thgroup_list): ditto; by moving gid clearance from
  rb_thread_cleanup().

* dir.c (fnmatch): "*/bar" (with FNM_PATHNAME flag) does not
  match "foo/bar".

* io.c (read_all): files on /proc filesystem with zero stat size,
  may have contents.

* ext/socket/socket.c (tcp_s_gethostbyname): refactored.

* ext/socket/socket.c (sock_s_gethostbyname): ditto.
